Terrestrial Microwave And Satellite Microwave

Terrestrial microwave transmission system satellite microwave transmission system.

Terrestrial microwave and satellite microwave. Reduced size weight. The rf link operates over a shorter distance and requires less power than a satellite equivalent. In this system attenuation mainly depends on frequency and signal strength. Microwave transmission uses very high frequency signals frequency range 300mhz 300ghz wavelengths range in air 100cm 1mm the two types of microwave transmission microwaves are electromagnetic waves microwave terrestrial satellite 1 2.

Advantages of terrestrial microwave over satellite. Attenuation is generally affected by the frequency and. Satellite or satellite microwave communication provides voice fax data and video services as well as email file transfer www internet applications. Microwave terrestrial satellite 2.

Microwave terrestrial satellite 1. Terrestrial microwave transmission is when microwaves are used to transmit data. Lower power means less weight smaller size and reduced power consumption. The transmit system converts baseband signal to microwave signal.

Ground based systems can use a tracking antenna. The frequency range needed is from 4 ghz to 6 ghz. In microwave radio relay microwaves are transmitted on a line of sight path between relay stations using directional antennas forming a fixed radio connection between the. The frequency range used in this system is between 11 ghz to 14 ghz.

Both of these systems require transmit part and receive part. Terrestrial microwave technologies share with satellite microwave technologies many of the scientific and technical improvements used to accomplish microwave transmissions. In case when the fixed wire terrestrial communication networks are crushed by a disaster then the satellite and microwave system as a emergency backup facility will be stressed. Microwave radio relay is a technology widely used in the 1950s and 1960s for transmitting signals such as long distance telephone calls and television programs between two terrestrial points on a narrow beam of microwaves.

Microwave communications are ideal for television and radio broadcasts while satellite communications are used for communicating to ships and aircrafts relaying telephone calls and providing communications to remote areas. Microwave communications are used for short range communications while satellite communications can be established over long distances.
